Chapter One   August 1, 1955 Groom Lake, one hundred miles northwest of Las Vegas, Nevada   Vance Shannon had made many first flights in experimental aircraft, but standing in the shadow of Kelly Johnson''s latest triumph, he was glad he wasn''t making this one. Called either the Angel, for its high-altitude capability, or the Article, as an informal code name, the beautifully strange aircraft was so secret that it had not yet been given an official designation.   Working with Kelly as a consulting engineer was difficult enough, for Johnson was a genius with a low tolerance for opposition or even suggestions unless they were overburdened with merit. But to be a test pilot for him was a nightmare, as the equally testy and opinionated Tony LeVier had long since discovered.   As he stood listening to their argument while trying not to appear to be eavesdropping, Shannon motioned Bob Rodriquez to his side. Bob had just been made a partner in Shannon''s firm, Aviation Consultants, something Vance had not yet disclosed to his twin sons, Tom and Harry, knowing that they would not approve.   "Listen to this, Bob; it''s a once-in-a-lifetime chance to hear a genius engineer and a genius test pilot going toe-to-toe!"   The short, dark, and handsome Rodriquez rather resembled a miniature Cesar Romero. He conscientiously cast his eyes up to the empty skies, appearing to be searching for a break in the clouds, as he listened to the increasingly loud argument.

  Kelly Johnson was big, five feet, eleven inches, tall and weighing well over two hundred pounds. He had developed his stevedore build--huge chest, massive arms and thighs--as a youth working in construction, making and putting up laths for plaster work in the days before drywall. All the muscle supported a giant intellect, for Kelly had earned stellar marks working his way through the University of Michigan, doing everything from washing dishes to subcontracting out the university''s wind tunnel for the design of Studebaker racing cars. Then he had talked his way into a job at Lockheed, where his first contribution was to criticize his boss''s design for a new transport--and be right.   From then on there was no stopping Kelly and all his personality quirks were overlooked in appreciation of his raw genius. As a boss, he could be a genial collaborator, given to spine-collapsing congratulatory slaps on the back. He could also be a monster, reacting chemically when he discovered an error and seldom hesitating to administer a good kick to the rear of the erring engineer. It could not be said that Kelly was loved by his subordinates, but he was admired enormously--almost religiously by some--for his brilliant insights, his ability to not only "see the air" around a new design but also sense intuitively the points where heat or stress or fatigue or production costs might be a problem.

  Today the problem was that Tony LeVier dared to have a different opinion. At forty-two, LeVier was only three years younger than Kelly, and as the dean of Lockheed test pilots was confident enough to stand up to Johnson in a way few men dared. Before the war, LeVier had set the pylons blazing at the Cleveland Air Races, flying cobbled-up aircraft with tiny wings and big engines. Lockheed hired him as a test pilot, and he became an expert in the P-38 Lightning, sent around the world to show pilots how to fly it with one engine dead, the propeller feathered. After the war he was the first to fly the F-94, the T-33, and Kelly''s latest product from the Skunk Works, the "missile with a man in it," the XF-104 Starfighter. LeVier had crashed at least eight times in his test work and was not a whit intimidated by Kelly. With the build of a rangy middleweight boxer, LeVier stood up straight in front of Kelly so that they went at it nose-to-nose.   Shannon dropped down and pretended to draw a sketch on the ground.

Rodriquez pretended to be absorbed in it as LeVier''s voice rose another octave.   "Goddammit, Kelly, you may be a great engineer, but you are no pilot. This bucket has a tail wheel, just like a Mustang or a P-47. I''m going to have to land it in a three-point attitude."   "You dumb son of a bitch, look at this airplane. Do you see three landing gears?"   Rodriquez''s face flinched; in his youth, insults like this would have meant a fistfight. He raised an eyebrow at Shannon, who looked down steadfastly at the meaningless drawing he''d made in the sand.   Kelly went on, "No, you see one undercarriage strut with two wheels in the middle, and one tiny wheel at the tail.

I want you to land on the main gear! But that''s not the problem. Look at that wing, for God''s sake."   It was an extraordinary wing to be sure, eighty feet long, narrow as a sailplane''s, and seemingly too fragile to bear the weight of the fuselage. Each tip was bent down, supported by an outrigger wheel that was jettisoned after takeoff.   "I don''t want you stalling this airplane! If you are just a little off in your judgment of height, or if you pick up a little lift from ground effect and stall it, you''ll drop it in and it will shed its wings like a snake sheds its skin."   LeVier was getting ready to counter when Kelly said, "Look, LeVier, case closed, land on the main gear like I''m telling you to, or I''ll get another boy."   LeVier said something too low for Shannon and Rodriquez to hear, but not for Kelly, who replied, "The same to you, LeVier. Now get your ass in that airplane and land it like I''ve told you to land it.

"   As the Lockheed ground crew busied itself, Shannon took Rodriquez aside.   "Don''t get the wrong impression. These guys are professionals, the best in the field, and they''ve worked together a long time. Kelly has a lot at stake in this airplane, and he absolutely cannot afford to have something go wrong. I''m surprised at his advice--I think Tony is right; he''ll need to land it like a conventional aircraft. But Kelly is a design genius, and maybe he knows something we pilots don''t know."   Rodriquez nodded toward the airplane, saying, "That thing looks like they took an F-104 fuselage and bolted glider wings to it."   "Looks like it.

But let me tell you the real story--it''s a knockout."   The clouds were still drifting over the field, freighted with rain and threatening to postpone the first flight for another day. Moving over to his maroon Cadillac Coupe de Ville, Shannon began his story, "By all conventional standards, that airplane should not be there. Kelly had been trying to sell the Air Force on the idea of a long-range reconnaissance plane for a couple of years, but the real impetus came from the Central Intelligence Agency. Now that Russia has the hydrogen bomb, and is building big bombers and maybe even intercontinental missiles, they have to get some hard information. It isn''t coming from anywhere else--Soviet security is virtually airtight."   Shannon pulled out a briefcase that contained two thermos bottles. "Water or coffee, or both?"   Rodriquez opted for coffee and said quietly, "Don''t stop now.

"   Shannon resumed, "The Air Force gave a contract to Bell Aircraft for twenty-eight planes, X-16s, they called them. Two engines, long, thin wing, somewhat the same formula as the Angel here, but bigger and heavier."   "Didn''t that freeze Lockheed out?"   "It should have, and would have anybody else but Kelly. It didn''t faze him a bit. He went to the Pentagon, sold his idea to some big wheels including Trevor Gardner and General Don Putt, and they went right to the secretary of the Air Force, a nice guy named Harold Talbott. Kelly Johnson promised to furnish twenty planes for twenty-two million, and to fly the first plane in eight months."   "Jesus, nobody could buy that."   "Well, that''s what Secretary Talbott thought.

He said, ''How do we know you can deliver?'' And General Putt says, ''He''s already proved it three times on previous projects''--meaning the XP-80, the P-80A, and the F-104. That did it! Talbott agreed to give Lockheed the contract."   "What about the Bell contract?" Rodriquez, almost compulsively straightforward, didn''t like what he was hearing.   "They canceled it, and it is sinking Bell; it may put them out of the fixed-wing business. That''s why Kelly is so fired up. His name, his reputation, maybe even his ass is on the line with this airplane. If this doesn''t work, he won''t be able to peddle apples in the Pentagon courtyard."   There was activity over by the Angel.

Tony LeVier, wearing his customary immaculate flight suit, was in the cockpit, with Kelly uneasily leaning from a maintenance stand, still talking a mile a minute.   Three days before, LeVier was making some taxi tests when a wind gust forced the Angel into an inadvertent takeoff. It flew for half a mile with the throttle at idle, then bounced heavily into the ground and spun around, blowing both main tires and setting the brakes on fire. For a breathless moment it seemed that the Angel might go up in flames, but the fire trucks, Johnny-on-the-spot, quickly suppressed the fire.   Remarkably enough, the damage was slight and easily repaired, but the incident made Johnson nervous and put LeVier under the gun. Both men had to prove themselves today.   Despite the lowering clouds and the prospects of a thunderstorm, LeVier applied power at five minutes to four and the Angel shot down the runway into.
